That may have been my fault. I mentioned that I used to have drug problems and mentioned specific drugs in one thread, so that may have set off the filters. I apologize if this is the case. The discussion about this went on for a day or two (involving maybe six comments). I do hope that is not the problem, but I will avoid such topics in the future to avoid any such issues.

Usually that sort of thing filters proxy servers too, but I've found that Google Web Transcode usually isn't blocked. Of course it strips stylesheets (and optionally images), but I usually consider that a feature.
